Abstract
Abstract A putting system for practicing and playing golf whereby a golfer is able to use the same putter in both a practice and playing mode. The club is adapted to be used with two interchangeable attachments. A first attachment provides spaced elements which are positioned on the striking face of the club to restrict the effective hitting area around the center of percussion of the club. The second attachment is interchangeable with the first and leaves the striking face of the club unobstructed while maintaining the same mass and weight characteristic to the club.
